Introduction
The Marine Corps, is organized as a general
purpose “force in readiness” to support national needs. Deploying for
combat as a combined-arms Marine Air/Ground Task Force (MAGTF), the Marine
Corps provides the National Command Authority (NCA) with a responsive force
that can conduct operations across the spectrum of conflict. The Marine
Corps’ most important responsibility is to win the nation’s battles.
2.
Mission
of the U.S. Marine Corps
The primary
mission, as stated in the National Security Act of 1947, “…is to provide Fleet
Marine Forces of combined arms together with supporting air components, for
service with the fleet...” This act also states that the Marine Corps minimum
peacetime structure shall consist of “…not less than three combat divisions and
three aircraft wings, and such other land combat, aviation and other services as
may be organic therein…” In addition, the Marine Corps maintains a fourth Marine
division and aircraft wing in reserve.
3.
Organization
and Structure
The Marine Corps is divided into four broad categories
Headquarters, U.S. Marine Corps:
Headquarters, U.S. Marine Corps (HQMC) consists of the Commandant of the Marine
Corps and those staff agencies that advise and assist him in discharging his
responsibilities prescribed by law and higher authority. The Commandant is
directly responsible to the Secretary of the Navy for the total performance of
the Marine Corps. This includes the administration, discipline, internal
organization, training requirements, efficiency, and readiness of the service.
Operating Forces: “The heart of the
Marine Corps.” It comprises the forward presence, crisis response, and fighting
power that the Corps makes available to U.S. unified combatant commanders. The
Marine Corps has permanently established two combatant command level service
components in support of Unified Commands with significant Marine forces
assigned: U.S. Marine Corps Forces Command (MARFORCOM) and U.S. Marine Corps
Forces, Pacific (MARFORPAC).
MARFORCOM
- Headquarters at Norfolk, VA
- Commands all Marine Corps operational and shore based
commands in the CONUS (less I MEF forces) Region
- Dual hatted commanding all Marine forces in the Southern and
European theater (MARFORSOUTH and MARFOREUR)
MARFORPAC
- Headquarters at Camp H.M.
Smith, HI
- Commands all Marine Corps operational and shore based
commands in the Pacific theater
- Dual hatted commanding all Marine forces in the Central theater
(MARFORCENT)
As a
student at Field Medical Training Battalion, you currently fall under The
Supporting Establishment. |
Marine Corps Reserve: The United
States Marine Corps Reserve (MARFORRES) is responsible for providing trained
units and qualified individuals to be mobilized for active duty in time of war,
national emergency, or contingency operations, and provide personnel and
operational tempo relief for active component forces in peacetime. MARFORRES,
like the active forces, consists of a combined arms force with balanced ground,
aviation, and combat service support units. MARFORRES is organized under the
Commander, MARFORRES. Their headquarters is located in New Orleans, LA.
Supporting Establishments: The
Marine Corps supporting establishments consists of those personnel, bases,
and activities that support the Marine Corps Operating Forces. The
supporting establishment also includes:
- Marine Corps Recruiting Command
- Marine Corps Combat Development Command
- Marine Corps Systems Command
- Training activities and formal schools
4. CHAINS OF COMMAND WITHIN THE
MARINE CORPS
There are two parallel chains of command within the Marine
Corps. Depending on the issue or task, they will either fall under the Service
Chain or the Operational Chain of Command.
The Service Chain of Command is used for things that are
specifically inherent to the Marine Corps. Examples would include anything from
purchasing new tanks to establishing rules for the use of tuition assistance.
Theses topics, whether large or small, only affect the Marine Corps. The top
portion of the service chain is listed below:
Service Chain
of Command
- President
- Secretary of
Defense
- Secretary of
the Navy
- Commandant of the Marine Corps
Authority for a USMC unit to move into Ramadi, Iraq in
2007 would have taken the following route:
- President: George Bush (Civ)
- SecDef: Robert Gates (Civ)
- U.S. Central Command: Admiral William Fallon (USN)
- Multi-National Forces Iraq: General David Petraeus
(USA)
- Multi-National Forces West: Major General Martin
Post (USMC)
|
The Operational Chain of Command is used to direct forces
in conjunction with operational or functional missions. Often times this
involves other services outside the Marine Corps. The Operational Chain of
command break down is listed below:
Operational
Chain of Command
- President
- Secretary of Defense
- Commanders of Combatant commands
5. Marine
Air/GROUND Task Force (MAGTF)
(see figure 1)
Definition and Purpose - the
MAGTF is a balanced, air-ground combined arms task organization of Marine Corps
forces under a single commander, structured to accomplish a specific mission.
It is the Marine Corps’ organization for missions across the range of military
operations. It is designed to fight while having the ability to prevent
conflicts and control crisis. MAGTFs are flexible, task-organized forces that
are capable of responding rapidly to a broad range of crisis and conflict
situations.
Capability
- all MAGTFs are task organized and vary in size and capability according
to the assigned mission, threat, and battle space environment. The MAGTF
is primarily organized and equipped to conduct amphibious operations as
part of naval expeditionary forces. MAGTFs are also capable of sustained
combat operations ashore.
Structure
- each MAGTF, regardless of size or mission has the same basic structure. A
MAGTF consists of four core elements: Command, Aviation, Ground, and Logistics
Combat Element. As the Ground Combat Element grows in size, the Aviation,
Logistics, and Command elements must also become larger.
Four Core Elements
of a MAGTF
a.
Command Element (CE) - the CE
contains the MAGTF headquarters and other units that provide intelligence,
communication, and administrative support. The CE is scalable and task
organized to provide the command, control, communications, computers,
intelligence, and joint interoperability necessary for effective planning
and execution of operations.
b.
Ground Combat Element (GCE) -
the GCE is task organized to conduct ground operations to support the MAGTF
mission. This element includes infantry, artillery, reconnaissance, armor,
light armor, assault amphibian, engineer, and other forces, as needed. The GCE
can vary in size and composition.
c.
Aviation Combat Element (ACE) -
the ACE conducts offensive and defensive air operations and is task organized to
perform those functions of Marine aviation required to support the MAGTF
mission.
d.
Logistics Combat Element (LCE)
- the LCE is task organized to provide the full range of combat service support
functions and capabilities necessary to maintain the continued readiness and
sustainability of the MAGTF as a whole. The LCE may vary in size and
composition.
6. TYPES
OF MAGTFS - there are four basic MAGTF
organizations: Marine Expeditionary Force, Marine Expeditionary Brigade, Marine
Expeditionary Unit, and Special Purpose MAGTFs.
Marine Expeditionary Force (MEF)
(see figure 2)
Definition
of Capabilities - the largest standing
MAGTF. The MEF is the principal Marine Corps war fighting organization. It is
capable of missions across the range of military operations, through amphibious
assault and sustained operations ashore in any environment. Each MEF is
comprised of a Command Element (CE), Marine Division (GCE), Marine Aircraft Wing
(ACE), and a Marine Logistics Group (LCE). The three standing MEFs provide a
reservoir of capabilities and combat power from which all smaller MAGTFs are
formed. There are three standing MEFs:
I Marine
Expeditionary Force (I MEF) - elements located in
California and Arizona:
1st Marine
Division (1st MARDIV) - Camp Pendleton, CA
3rd Marine
Aircraft Wing (3rd MAW) - Miramar San Diego, CA
1st Marine Logistics Group (1st MLG) - Camp Pendleton, CA
II Marine
Expeditionary Force (II MEF) - elements
located in North and South Carolina:
2nd Marine Division (2nd
MARDIV) - Camp Lejeune, NC
2nd Marine
Aircraft Wing (2nd MAW) - Cherry Point, NC
2nd Marine Logistics Group (2nd MLG) - Camp Lejeune, NC
III Marine
Expeditionary Force (III MEF) - elements
located in Hawaii and Japan:
3rd Marine
Division (3rd MARDIV) - Okinawa, Japan
1st Marine
Aircraft Wing (1st MAW) - Okinawa, Japan
3rd Marine Logistics Group (3rd MLG) - Okinawa, Japan
Each MEF is
commanded by either a Lieutenant General or Major General and consists of
anywhere from 20,000 to 90,000 personnel. A MEF generally deploys on Amphibious
Assault Ships with support from Military Sealift Command (MSC) and Maritime
Pre-positioned Force (MPF) vessels and takes with it 60 days worth of supplies.
Marine Expeditionary Brigade (MEB)
(see figure 3)
Definition of Capabilities -
this is a medium sized non-standing MAGTF that is task organized to respond
to a full range of crises, from forcible entry to humanitarian assistance.
MEBs are not standing forces, and are formed only in times of need. An
example is post 9/11, the 4th MEB and 2nd MEB were
formed to respond to combat and peacekeeping contingencies in Afghanistan
and Iraq.
A MEB is commanded by a
Brigadier General or Major General and consists of anywhere from 3,000 to
20,000 personnel. It also generally deploys on Amphibious Assault Ships
with support from Military Sealift Command (MSC) and Maritime
Pre-positioned Force (MPF) vessels and takes with it 30 days worth of
supplies.
Elements consist of:
Command
Element (CE)
Ground Combat
Element (GCE) = Marine Regiment (MARREG)
Aviation Combat
Element (ACE) = Marine Aircraft Group (MAG)
Logistics Combat Element (LCE)
= Combat Logistics Regiment (CLR)
Marine Expeditionary Unit, Special Operations Capable (MEU
(SOC)) (see
figure 4)
Definition of Capabilities
- the standard forward deployed Marine expeditionary
organization. A MEU is task organized to be a forward deployed presence and
designed to be the “First on the scene” force. A MEU is capable of a wide
range of small scale contingencies, to include:
- Noncombatant evacuation
- Maritime interdictions
- Tactical recovery of aircraft and/or personnel
- Humanitarian/civic actions
- Military operations other than war.
Prior to deployment, a MEU undergoes an intensive six month
training program, focusing on its conventional and selected maritime special
operations missions. The training culminates with a thorough evaluation and
certification as “Special Operations Capable (SOC).” In addition to possessing
conventional capabilities, MEU (SOC)s are augmented with selected detachments to
provide enhanced capabilities.
A MEU is commanded by a
Colonel and consists of anywhere from 1,500 to 3,000 personnel. It
generally deploys on naval vessels and takes with it 15 days worth of
supplies.
Elements consist of:
Command Element (CE)
Ground Combat Element (GCE) =
Marine Infantry Battalion Landing Team (BLT)
Aviation Combat Element (ACE) =
Composite Marine Squadrons (Rotary wing with a complement of fixed wing
aircraft, depending on mission)
Logistics Combat Element (LCE) =
Combat Logistics Battalion (CLB)
Definition of Capabilities -
the SPMAGTF is a non-standing MAGTF temporarily formed to conduct a specific
mission. It is normally formed when a standing MAGTF is unavailable or
inappropriate. Their designation derives from the mission they are assigned,
the location in which they will operate, or the name of the operation in which
they will participate. (i.e., SPMAGTF Somalia, SPMAGTF Katrina etc.). These
MAGTFs vary in size and composition based on the individual mission.
